Application July 24, 1946, Serial No. 685,988

1 Claim. 1

My present invention relates to an improved staple extension forpadlocks and more especially to the type of extension which may beemployed where a spaced pair of lock receiving loops would normallyrequire a padlock having a hasp of abnormal length.

Generally my invention comprises an elongated staple adapted to have oneleg thereof inserted through the spaced loops and formed with means forreceiving and securing a conventional padlock with a normal hasp.

In the accompanying drawings I have i1lustrated one complete example ofthe physical embodiment of my invention according to the best mode Ihave thus far devised but it will be understood that various changes andalterations may be made in the exemplified structure within the scope ofthe appended claim.

In the drawings--' Figure 1 is an assembly view showing the elongatedstaple of my invention associated with a pair of spaced loops and with apadlock on the staple.

Figure 2 is an end elevational view thereof.

Figure 3 is a top plan view of the staple.

In the embodiment of my invention presently illustrated I employ withthe closures 2 and 4, the loops 6 secured to plates 8 and these platesare attached to the respective closures by screws Ill. Normally tosecure the closures by means of these securing loops, a padlock with anabnormally long hasp would be required. According to my inventionhowever, a conventional padlock may be employed with the staple of myinvention.

The staple of my invention is of one-piece construction, and consists ina metal rod of substantial diameter not subject to easy bending andincluding the straight leg it free of projections and bent as at 14 toform the parallel leg l6 which is also bent at the free end as at 18 toform the closed loop 20. The leg [6, with loop 20 formed 2 thereon, issubstantially shorter than the leg II. The straight leg of the staple ispassed through the two spaced securing loops of the closures and thepadlock Z2 is secured onto the staple by placing the hasp 24 through theclosed loop 20 and about the leg 12 as shown.

The staple may be made of any desirable length and of material ofsuitable strength in order that the closure loops of various design andoperation may be accommodated.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

A one-piece extension staple for a padlock and its hasp comprising alength of rod material integrally formed with a bend intermediate itsends, and spaced straight parallel legs extended from the bend, one legbeing shorter than the other and being bent upon itself at its free endin a direction away from the longer leg to provide a loop through whicha hasp may be extended, all portions of said loop being disposed on theoutside of said staple and clear of the space between the legs, thelonger leg being free of projections.
